Mag 533 reading blank DVD-Rs as full
I've finally gotten around to trying systematically to back up the programs on the hard drive on my Mag 533H/F7 by dubbing to DVD-Rs. Had been going well for a week or so but today when I set up 6 programs to dub to a disc and clicked on "dubbing start", the Mag replied with "Disc is full. Cannot dub to this disc."
The DVD-Rs I've inserted are unquestionably empty. I noticed that in some cases when I insert them, after the loading has finished the display shows a value of -2:00:00.
I noticed in a thread from quite awhile back that Wajo suggested to someone with a different problem that they try a soft reset. How does one do that?
Thanks very much for suggestions.
